Feb. 25, J. G. BLUNT 4 HUB LINER FOR RAILROAD VEHICLES Filed Feb. 9. 1928 WITNESSES wf Mi Patented Feb.,25, 1930' matte- JAMES G. BLUNT, F SGI-IENECTADY, NEW YORK HUB LINER non nAinnoAn VEHICLES Application filed February 9, 1928. Serial No. 252,987.-

This invention relates to appliances of the general class or type known as hubrliners, which are interposed between the journal boxes of railroad vehicles and the Wheel hubs adjoining them, for the purpose of absorbing lateral pressure in passing around curves. The type referred to is instanced in Letters Patent of the United States No.'1,551,005,

granted and issued to James G. Blunt, under date of August 25, 1925*,upon whichthe pres ent invention is aniniprovement.

The object of the invention is to provide a hub liner having the operative advantages of that set forth in Patent No. 1,551,005 aforesaid, and in addition, the structuraladvant'age of capability ofapplication in connection with journal boxes ofsuch form' as would preclude the applicability ofthe hub liner of said patent. V j

The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure 1 is a vertical axial section, through a journal box and wheel hub, illustrating an application of the'invention in connection therewith; Fig. 2, a side View, in elevation, of the hub liner; and, Fig. 3, a View, in perspective, on an enlarged scale. r

In the practice of the invention, referring descriptively to i the specific embodiment thereof which is herein exemplified, wear plate, or liner, 7 end of a journal box, 1, and the hub of the adjacent wheel, l, said liner beingof sectional construction, and comprisingtwocounterpart members, or sections, 2, 2. The two sections abut, one against the other, in the.

vertical axial plane of the liner, and are de- 40 tachably connected by a bolt, 3, passing through boltinglugs, 2 one at the bottom of each of the sections. The bolt, 3,is drawn to a tight bearing by a nut, 3

In applying the hub liner, the'sectionsfmay be separately slipped upward to position,

relative to the axle, 4*, without dropping the wheels, and when in position, are supported on the journal box by inwardly and downwardly inclined dove-tailed tongues, 2

one on each of the sections, and thereafter is interposed between the outer boltedtogether at their necting'bolt, 3. f 5 an open'top oil recess, or recesses, formed in each ofthe sections, fromfwhich oil is supplied. to the face of the hub liner,

bottoms, by the may be through passages,-2. Thejoil recess, oiling V grooves, andtongu'es are substantially similar to the corresponding members of the hub liner of- Patent No.1,551,005 aforesaid, and do'notform part: of the pres'ent invention.

It will be obvious to those familiar with the construction of railroad'rolling stock, 7

that the invention herein set forth is of substantial practical value :in the capability which it affords of application in connection with journal boxes of types now in service; in which the space above the hub liner is o so limited by other members asto render it impossible to locate a connecting bolt in such space: Further, the capability of inserting thehub liner from below, without "dropping the wheels, is a valuable feature.

The invention claimed'as new and desired to be secured by Letters Patent is: -1. A hub linercomposed of two counterpart sections, each section'having a face at the top portion adapted to be opposite a face of upper portions adapted to cooperate with an the other section when the sectionsareas V I 'sembled, and an lnner face having side and inner face of the other section having side i a'ndupp'er portions, when the parts are assembled, to surround the sides and top of a portion of the journal; a tongue projecting from each of the sections adapted'to fit in a directed for assembling the sections by movements thereof toward the vertical axial plane of the journal {and means for'engaging thesections at the bottom, thereof for securing the sections together. i a

2. A hub liner composed of two 'counter part sections, each section having a face at the 1 top portion adapted to be opposite a face of s5 groove in the journal box, the'tong'ues being I tion of the journal; an inclined tongue projecting from each of the sections directed upwardly toward said top face and adapted to fit in a groove in the journal box, the tongues being directed for assembling the sections by movements thereof upwardly and towards the vertical axialplane of the journal; and

means for engaging the sections at the bot tom thereof for securing the sections together.

3. A hub liner composed of two counterpart sections, each section having a face at v the top portion adapted to be opposite a face of the other section when the sections are as sembled, and an inner face having side and upper portions adapted to cooperate with an inner face of the other section having side and upper portions, when the parts are assembled to surround the sides and top of a portion of the journal; an inclined tongue having a bevelled face projecting from each of the sections, directed upwardly toward said top face adapted to fit in a similarly bev elled groove in the journal box, the tongues being directed'for assembling the sections by movements thereof upwardly and towards the verticalaxial plane of the journal; and means for engaging the sections at the bottom thereof for securing the sections together.

4. A hub liner composed of two counterpart sections each section having a face at the top portion adapted to be opposite a face of the other section when the sections are assembled, and an inner face having side and upper portions adapted to cooperate with an inner face of the other section having side and upper portions, when the parts are assembled to. surround the sides and top of a portion of the journal; an inclined tongue having a bevelled face projecting from each of the sections, directed upwardly toward said top face, adapted to fit in a similarly bevelled groove in the journal box, the tongues being directed for assembling the sections by movements thereof upwardly and towards the-vertical axial plane of the jour- 11211; a. flange projecting along the bottom edge of therliner having an outwardly and upwardly bevelled upper face adapted to engage a correspondingly bevelled face along thebottom of the-journal box, for cooperating: with the engaging bevelled faces of the tongues to-secure the liner against displacenie'nt in an axiald-irection; and means for securing the sections together.
